Fluffy Japanese Cotton Cheesecake Cupcakes

by

Of course! Japanese Cotton Cheesecake is famous for its incredibly light, jiggly, and fluffy texture. Turning them into cupcakes makes them perfectly portioned, easier to bake, and adorable.

This recipe uses a bain-marie (water bath) method for each cupcake to create that signature moist, delicate crumb.

Fluffy Japanese Cotton Cheesecake Cupcakes

These cupcakes are a cross between a classic New York cheesecake and a soufflé. They are subtly sweet, with a rich cheese flavor and a cloud-like texture.

Ingredients

· 4 large egg yolks (at room temperature)
· 2 large egg whites (at room temperature*)
· 6 oz (170 g) full-fat cream cheese, softened
· 3 oz (85 g) unsalted butter (plus extra for greasing)
· 1/3 cup (80 ml) whole milk
· 1/4 cup (30 g) cake flour (sifted)
· 2 tablespoons (20 g) cornstarch (sifted)
· 1/3 cup (65 g) granulated sugar, divided
· 1 tablespoon fresh lemon juice
· 1/2 teaspoon vanilla extract
· A pinch of salt
· Powdered sugar for dusting (optional)

*Why room temperature eggs? Egg whites at room temperature whip up to a much greater volume, which is the key to the fluffy texture.

Instructions

Step 1: Prepare for Baking

  1. Preheat your oven to 320°F (160°C).
  2. Generously grease a standard 12-cup muffin tin with butter or non-stick spray. Line each cup with a parchment paper liner. (Regular cupcake liners can stick; parchment is best).
  3. Place the muffin tin inside a larger, deep roasting pan. Put a kettle of water on to boil for the water bath.

Step 2: Make the Cheese Batter (Chiffon Base)

  1. In a heatproof bowl, combine the cream cheese, butter, and milk. Set the bowl over a pot of simmering water (double boiler), making sure the bottom of the bowl doesn’t touch the water.
  2. Whisk continuously until the mixture is completely smooth and lump-free. Remove from heat and let it cool slightly.
  3. Whisk in the egg yolks, lemon juice, and vanilla extract until fully incorporated.
  4. Sift the cake flour and cornstarch into the cheese mixture. Whisk vigorously until you have a smooth, thick batter. Set aside.

Step 3: Whip the Meringue

  1. In a completely clean, dry, and grease-free bowl, beat the egg whites with a pinch of salt on medium speed until foamy.
  2. Gradually add the sugar, about 1 tablespoon at a time, while beating on medium-high speed.
  3. Continue beating until you reach soft peaks—this is crucial. The meringue should be glossy and white, and when you lift the beaters, the peak should curl over gently. Do not whip to stiff peaks, as this can make the cakes crack.

Step 4: Fold and Combine

  1. Take about 1/3 of the meringue and whisk it into the cheese batter. This will lighten the thick batter and make it easier to fold.
  2. Gently fold in the remaining meringue in two additions using a spatula. Use a cutting and folding motion to retain as much air as possible. Stop as soon as no white streaks remain. Do not overmix.

Step 5: Bake with a Water Bath

  1. Divide the batter evenly among the prepared muffin cups, filling them about ¾ full.
  2. Carefully place the entire roasting pan with the muffin tin inside into the preheated oven.
  3. Pour the hot water from the kettle into the roasting pan until it comes about halfway up the sides of the muffin tin. Be careful not to get any water in the batter.
  4. Bake for 25-30 minutes, or until the tops are a light golden brown and the cakes spring back lightly when touched. They will have puffed up beautifully.

Step 6: Cool Properly (This Prevents Collapse)

  1. Turn off the oven and crack the oven door open with a wooden spoon. Let the cupcakes sit in the cooling oven for 10-15 minutes. This gradual temperature change prevents them from sinking.
  2. Carefully remove the roasting pan from the oven, then remove the muffin tin from the water bath.
  3. Let the cupcakes cool in the tin for another 10 minutes before transferring them to a wire rack to cool completely. They will deflate slightly as they cool—this is normal!
  4. Chill in the refrigerator for at least 2 hours before serving. They are best served cold.

Pro Tips for Success

· No Curdling: Ensure your cream cheese and butter are truly softened to room temperature to avoid a lumpy batter.
· Gentle Folding: Overmixing the meringue will deflate the batter and result in dense cupcakes. Be patient and gentle.
· The Meringue is Key: Soft peaks are non-negotiable. Stiff peaks create too much tension, causing the cakes to rise rapidly and then crack and collapse.
· Water Bath is Mandatory: This is the secret to the moist, creamy texture. It provides gentle, even heat.
· Serve Chilled: These cupcakes taste much better after a few hours in the fridge. The flavors meld and the texture sets perfectly.
· Garnish: Dust with powdered sugar just before serving for a beautiful, simple finish.
